Lux AI Supercomputer Arrives at Oak Ridge National Laboratory
- The Lux AI supercomputer was delivered to the Oak Ridge Leadership Computing Facility at ORNL on Wednesday 17 June 2026, the delivery marking the start of its installation and deployment[3].
- A month later, on 17 July, Lux, built by HPE with AMD technology for DOE's Genesis Mission, was undergoing installation and final integration in the data center[4].
- Lux carries more than 4,000 AMD Instinct MI355X GPUs in over 500 nodes with 1.1 PB of HBM, rated at 20 exaflops for FP8 AI training and 317 petaflops at FP64, with a 400G Ultra Ethernet NIC per GPU and both Slurm and Kubernetes[1].
- It is built on HPE's direct liquid-cooled ProLiant Compute XD685 servers with AMD EPYC CPUs and Pensando networking[5].
- DOE announced Lux on 27 October 2025 alongside Discovery, the successor to Frontier due in 2028, saying Lux would be deployed in early 2026 under a new public-private partnership[6].
- Half of Lux's 3.5 million node-hours a year go to the Genesis Mission and the rest to paid access; AMD co-invests with DOE and will use some of the cycles for development and testing[1].
- Lux runs under DOE Moderate security controls, like Frontier, which allow export-controlled applications and data[1].
- HPE said in July 2026 that Lux is expected to be the first dedicated AI system for science supporting the Genesis Mission[2].

The Lux page shows the photo 'The Lux supercomputing system arrives at ORNL[3][4][6]' without a date; that photo's own OLCF page dates it: 'Lux supercomputing system on Wednesday, June 17, 2026 in the Oak Ridge Leadership Computing Facility. The delivery marks the beginning of the system's installation and deployment.' No time given, so all day.

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
